It's probably not worth it for stress most of the time, but as noted, it's a cheaper option for Shuttles to stay in the fight a little more.
But against Ion? Ion can just about be a death sentence. A 1pt option to trade a damage to be able to flee could be worthwhile indeed. With TLT shouldering out IonHogs in the meta, this probably isn't as obvious as it once was. But TIE/D Defenders will be bringing that back, baby - it's a useful counter-pick.
